CUTTING OR SLICING- MACHINE'.

Application filed March 30, 1926. Serial No. 98,550.

This invention relates to a cutting or slicing machine especiallyadapted for use in forming thin sheets or plates of vvood.

One of the principal objects of the invention is to provide a machine ofthis character which is especially adapted to produce battery separatorsout of small blocks or Waste lumber that now can only be used for fuel.The invention is also adapted for use l0 in producing` thereinsheet-like veneer stock which may be employed in the construction ofberry baskets as Well as in other uses.

An important advantage of the present invention when used to produce aseparator for batteries resides in the fact that the present machine maybe employed to make vertical grain separators as Well as fiat grainseparators.

In carrying out the present invention a ing a` machine embodying thepresent invention, j

Figure 2 is a plan view thereof, A

Figure 3 is a fragmentary detail view in vertical section taken on theline 3-3 of Figure 2, j

Figure 4 is a vievv in vertical section taken on the line /1-4 of Figure2, j

Figure 5 is a. view showing the main wheel in front elevation, theassociated parts of the frame and the shaft on which the Wheel iscarried being shown in section,

Figure'6 is a fragmentary view in elevation of a portion of the otherface of the Wheel from that shown in Figure 5, and

Figure 7 is a detail sectional view on the line lL-7 of Figure 6.

Referring to the Vdra-Wings it will be seen thatthe machine includes asuit-able frame main vrotary Wheel is provided and on ther Figure 1 is avievv in side elevation show-` 1 on which bearings 2 are provided. Amain shaft 3 is rotatably fitted in the bearings 2 and between thebearings 2 a main Wheel 4; is liXed to the shaft 3. The Wheel t consistsof a disc-like plate of metal or other suitable material Which maybethickened at its hub and Banged at its rim, the body of the Wheel being`formed With a flat surface lla. This body of the Wheel is also providedwith a plurality of spaced openings 5, the openings 5 inthe presentembodiment of the invention being indicated at angular intervals of 90".As shown in Fig. 3 the Walls of the openings 5 are preferably steppedand present a flange 5a at the inner face or fiat face 4a of the Wheel4. In each of the openings 5 a circular cutter carrier 6 is adjustablyfitted, the periphery of the carrier 6 being stepped to correspond withthe vvall of the opening 5 in which it is `lit-ted. The steppedformation of the periphery of the carrier 6 provides a flange 6n whichfits against the flange 51.` A. plurality of attaching ears 7 areintegrally formed With each carrier 6 and these attaching ears co-actwith stud bolts or other fastening means 8 to secure the carriers to thevvheel with their flanges 6a engaging the flanges 5a. rBy providingslots in the ears 7 or by providing a plurality of bolt holes in theWheel l around each opening 5 the carriers 6 may be angularly adjusted1n their openings and secured in any desired adjustment.

Each carrier 6 is provided with an inclined opening 10 extendingtherethrough and diametrically thereof. An enlargement 11 is integrallyprovided on each carrier and has one face which merges into one Wall ofthe opening 10, the enlargement thus aiding in providing a seat 12 for aknife or cutter 13. Each knife or cutter 13 is provided with a pluralityof spaced slots 14 with` which bolts 15coact to secure the cutter orknife in adjusted position on its seat, as illustrated to advantage inFigs. 3, 6 and 7. As shown Vin Fig. 3 each cutter or knife has an edge16 which projects through the opening 10 and slightly beyond the innerface la of the Wheel 4. The knives 13 do not lill the openings 10 butleave spaces 17 through which the severed sheets or plates of Wood pass.Adjacent to or opposite'the edge 16 of Veach knife a presser bar 18 isprovided, each presser bar being adjustably' suppcrted a groove 3.9provided in each carrier 6 1 fitted.

`thereto" laterally extending V4avall 'is provided with upward-ly extending invented *vf-shaped ribs 29 and on ,these ribs'ZS) a sliding orshiftable anvil 30 is supported, the anvil 3@ having inverted V- shfapedgrooves 3l in which the `ribs Q9 are y Vhe anvilBO has integrally formedtherewith -or otherwise igidly connected ytru-nnions v32, -on which`rollers 33 are iitted. One enid of a rod 34 is'connected with eachtrunfnion 32, and the Aother end of each rod 34 is slidable Vthrough anopening `35 in the Wall 28. Coniipression Icoilsprings 36' are mountedV'on the 'rods 84 and one end -of each: ccoi'l :spring .35

"eng-ages the vend Wall 2.8, the lother rend of such coil springengaging an adjustable -abutmentlSY which may take .the form of anutst'hreadedly connected With the rod The coil springs BZztend to'project the anvil l30 toward the Wheel 4 as A:tar as itin'ay be Iprojected. This action of the coil springs perI l "around sprocket`Wheels 42 "fixed onv shafts is limited fby means of nuts y38 threadedon 'the rearwardly extending lends of the rods andhaving Washers 39associated therewith.

' Feeding mechanism is provided for feeding theblock-s B oit' wood orthe .other stock Y to vbe spliced across the table y25 onto the ani vil'30 and against `the dat surface 4 of the `Wheel 4 Where'these blocksWill corne into the iield ot operation of the cutters orknivesmounted'on thg'aca-rriers of 'the wheel. 'This feeding mechanismpreferably consists of upper-and flower pairs 'of sprocket chains,indicated at -40 and4lrespectively, the upsprocket chains 40" beingVthreaded 43, the -lotver sprocket chains 41 lbeing ytrained aroundsprocketiivheels 44 iiXed on `rlhewsh'atts 43 .are rotatable in bearings46- provided at the upper ends of bearing brackets 47, the lovver ends:ofthe bearingv brackets 47 being secured tothe table Q5. The shafts arerotatable in bearings 48 :carried by the underside of the table 25. Asshown toadvantage in Fig. 4 the lower sprocket chains 41 operate inslots f5() forinedfinvthe table 25 and extending lengthvvise'thereof.The upper runs of the sprocket chains 50 proj ectV slightly above thetablefso` asftoha've -:the desired -trictional .en-

w y At this point itishould be noted that theblocks B or stock is drivenby virtue of the rictional engagea-t one end VAot a table nient of thesprocket chains `therewith and this permits or the desirable slippageoccurring in certain phases ot' the operation. rThe in achine isyprovided WithA a drive shattY GQh-avin'g a 'prilley Gl fixed thereto.and adapted to be driven from a motor, line shaft orany other suitablesource of power. This sha-tt `-6() is journaled in suitable bearings 62providedV therefor in the traine l and vhas ai pulley '63 .and servingto drive a pulley 64 iixed to the shaft 3 through the inediunio'i a beltr-trainedover Vthe pulleys '6:3 and 64. The sprocket. chains `40 and 4lare also driven from .the shatt `@Oby means o- :suitable vgearing -ormotion transmission means which is shown as 'comprising` a verticalshaft 66 driven from the shaft 60 by means 'of beveled gears 67, thevertical shaft 66 ser-ving to drive one ot the shafts :45 throughbeveled gears 68. The shafts 43 are driven Vfrom one of thef shatt-s 45`by means of belt and pulley gearing '710.

In the 4operation ot the machine the blocks :are fed up against theace141L of the Wheel V4 by the sprocket chains 40 andj41 and when ablock 4is `forced againstv the tace 4 of the Wheel 4 itrests on theanvil 8,0 and is inthe field o action :or movement of the knives or4"cutters 13;' `These knives or cutters are mounted on the carrierswhich may-be adjusted to carry the knives at the desired incline orangularity that Iresults in the sweeping across the block YWith a'sliding cut, thereby enhancing lthe-cuttingaction ln order to canse theanvil 30 to be retractedl to permit :the bla-desto pass the :samescaniming ribs A80 areprov-ided'on each carrier `and are engageable Withthe rollers 30 to automatically retractv the vanvil at the proper timein the vlcycle cfcperation. This action alsoretracts the anvil toprevent the last thin slice of a block fronibeing jammed in between theanvil and the Wheel.`
